(Corrects attorney Austin Hinkle's title in 21st paragraph)By Douglas GillisonWASHINGTON, Aug 4 (Reuters) - A top supervision examiner at the U.S. Consumer Financial Protection Bureau warned staff they would face "most unpleasant" consequences if they were too aggressive in their oversight of financial firms, according to an internal email reviewed by Reuters. Critics say the message amounts to a threat to CFPB staff that would likely make them think twice about how they interact with companies they oversee. Representatives for the CFPB and the White House did not respond to requests for comment. Under Vought, agency leadership has accused staff ⁠of "thuggery" in dealing with the companies they oversee. Batie emailed staff in May as exams restarted, adding a "friendly reminder...to be careful" in light of that pledge.
